GIMP plugins have individual licences. What license they have can be seen in the GIMP Plugin Registry. Chroma Key is licensed under the BSD-license which means you are free to use it for commercial purposes.

I can not say for sure, but I think all official GIMP Plugins (which are those available at registry.gimp.org) are required to be under FSF-approved free software licenses, which means they can all be used commercially.

Who defined those as official? Anyone can upload stuff there - or could, as the spammer problem has never been resolved, so it is now limited to the already existing users.

Drupal - at least the version used there - doesn't make the fight against spam an easy task, unfortunately. The fact that we don't control the server ourselves limits our actions.

I don't think that a review of that has been done. A quick check found one plug-in under a NC license: http://registry.gimp.org/node/28271

Then it seems my assumption was wrong.

I guessed this because GIMP is part of the GNU-project (hence the actual name: Gnu Image Manipulation Program) which requires all licenses to be FSF-approved. But perhaps the registry is not an official part of GIMP. Probably not, since NC-licenses are allowed.

In fact, the "official" plug-ins are all those that are shipped with GIMP source code - and only those.
These official plug-ins are under GPLv3 or later, just as GIMP itself.

Everything else is not covered - and each plug-in might have its own license. I remember several years ago about a discussion on the developer list about that there should bean explicit exemption of the GPL for third party plug-ins (since, for example, there was even a plug-in that allowed use of photshop binary plug-ins at the time). - and the result of that discussion it is there in the "LICENSE" file that ships with the source code (pasted bellow).

Regards,

js -> file in the
libgimp directory for details.

Each plug-in comes with a license, so as long as the license is GPL, there are no restrictions as to where you are using the produced images.
I could not find "Chroma Key". However, for "Chroma Denoise", the license is GPL (see: http://registry.gimp.org/node/25452), so that would be safe to use.

You would have an issue if the license had a clause "Not for commercial use". However, the GPL license does not allow such clauses, so if the license is GPL (any version), you can use the software for commercial work.
